Love it or Loathe it: Katy Perry's Sheer Dress

Despite the reports that Katy Perry is broken up over her very-public split from John Mayer, it doesn't look like the songstress has spent too much time sulking.

The divorced-then-dumped singer celebrated a close pal's birthday this weekend and was snapped leaving the party in this super-sexy, ultra-sheer dress that, well, doesn't leave much to the imagination.

The 27-year-old accessorized the see-through floral maxi with a pair of, yes, belly-grazing panties and showed off her taste for edginess in a studded biker jacket and clunky boots.

Hmm... Perhaps this is her way of sending a quite literal "See what you're missing" shout-out to Mr. Mayer?

What do you think about the pop star's daring dress of choice? Is it a chart-topping sizzler or just a bad break-up tune? Let's put it to a vote, shall we?
